The goal is to construct a grouped frequency distribution table (GFDT) for this data set. The GFDT should have 10 classes with a "nice" class width. Each class should contain its lower class limit, and the lower class limits should all be multiples of the class width.

This problem is to determine what the class width should be.

What is the maximum of this data set?
max =
679
Correct

What is the minimum of this data set?
min =
242
Correct

What is the range of this data set?
range =

What is the (most likely) discrete unit for this data set?
discrete unit =

What is the span of the range?
span =

Using this value, if the goal is to have 10 classes, what is the nicest class width?
optimal class width =
